Ultrasound-Guided, Continuous Brachial Plexus Blockade in a Neonate With Upper Extremity Limb Ischemia: A Case Report.

Regional anesthetic blocks, especially in-dwelling catheters, are infrequently used in neonates and infants.

A brachial plexus catheter was placed using ultrasound guidance, and a continuous infusion of a local anesthetic was used to provide postoperative pain control.
